JEAN NADAL, or PARIS, FRANCE.

STUD OR FASTENING FbR SHlRT-WRISTBANDS, 800.

SPECIFICATION forming part of Letters Patent o. 528,339, dated October 30, 1894.

Application filed October 2, 1893-1 Serial No. 487,004. (No model.)

To all whom it may concerns Be it known that I, JEAN NADAL, of the city of Paris, France, have invented Improvements in Studs, Buttons, or Fastonin'gs for Shirt Wristbands or Cuffs and the Like, of which the following is a full, clear, and exact description.

My invention relates to an improved stud, button or fastening for shirt wristbands or cuffs and other articles of wearing apparel in which the disk constituting the back is formed in two halves capable of being expanded to secure the stud or button in position and of being contracted or brought into line with the pillar to facilitate the insertion of the button in the button hole or its withdrawal therefrom, and my said invention consists in the combination and arrangement of parts hereinafter described and set forth in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification; wherein- Figure 1 represents a side elevation of the button showing the narrow side of the pillar or shank, the folding back being expanded, and Fig. 2 is a plan view of the same, while Fig. 3 is a sectional view of the button on line 3-3 of Fig. 2. Fig.4 is a fragmentary detail view partly in section of the top of the pillar taken on line 4=4. of Fig. 2. Fig. 5 is alongitu dinal sectional elevation of the pillar showingthe back folded in line with the shank or pillar. Fig. 6 is a broken-away longitudinal sectional elevation taken at right angles to Fig. 5. Fig. 7 isafragmentary detail view of a portion of the button looking in the direction of the arrow in Fig. 3. Fig. 8 is a crosssection of a modification of my invention.

Fig. 9 is a section of the same taken on line 99 of Fig. 8 and corresponding to a section on line 99 of the form shown in Fig. 2. Fig.

10 is a sectional view of the same showing the Wings closed; and Fig. 11 is a'detail view of a part to be described.

Referring to the drawings, the button is composed of the head j, the hinged back made in halves d d, and the pillar b formed in one with the flange or disk a. The head j and the pillar b are revoluble with relation to each other. The pillar is preferably of oval form in cross-section to conform as near as possible to the shape of the button-hole and it is provided at the end opposite to disk a with ears f in which the pivots c on knuckles e of the two semi-circular wings d d constituting the back 'are mounted.

' g is the shank of a T-shaped piece which isreceived within the pillar b and passes through a'spring h which is adapted to be compressed between the head j and the disk (1.. This shank g of the T-shaped piece, after passing through the spring it extends into the head j to which it is keyed, by being flattened at 2' and fitting in a corresponding hole in the said head j so as to prevent the two parts from turning independently of one another, or it may be fastened inany other desirable manner. The shank g is secured in the headj by a fork k slipped in notches made in the end t'of the shank, or a cross-pin passing through theend of the shank or other analogous device may be employed.

1 The wings d d constituting the folding back T are operated by means of the T-shaped piece, (which maybe turned in either direction,) the shank g of which is rigidly connected with the headj as already described. The knuckle e of the hinge of the wings d is formed with a. central aperture Z (see Fig.2) for the shank g to pass through and the knuckle is cutaway at m m to form'suitable cam surfaces with which the arms at n constituting the head of the T-piece come in contact as the T-piece is rotated with relation to pillar b, so as to cause the wings d d to gradually close until they meet and form virtually a continuation of the pillar b. WVhen the wings are in this position the arms at n bear upon the flat shoulders 0 (Fig. 10)'of the knuckle and bythe pressure of the spring h retain the wings in this position. (See Fig. 5.) 'By reversing the action or by continuing to rotate the head'j the arms a will be disengaged'from the shoulders 0', and in passing over the cam surfaces mwill open out or expand the wings. When- In using the button, the head j is rotated upon the pillar I) either for the purpose of expanding the wings d (I, when the stud or button is to be secured in position on the cuif, or for closing the two wings face to face to allow of their being passed through the button hole, when inserting or removing the stud.

Figs. 8 to 11 represent a modified arrangement in which the wings forming the back of the stud or button are caused to close toward each other and retained in that position by means of springs r contained within the pillar b. \Vhatever kind of spring be employed it must not in any way prevent the insertion or impede the action of theT-shaped piece which serves to cause the closing and expanding of the wings as before.

In Fig. 8 two steel wire springs are shown mounted within the pillar, toward either side thereof, so as not to interfere with the hinge or T-shaped piece.

The employment of springs it will be understood is optional. When they are not used the wings may be closed by simply drawing them through the button-hole after the T- shaped piece has been placed parallel with the hinge. Instead of each wing being separately hinged the hinge by which they are connected to the pillar may be common to both.

In the modification represented in Figs. 8 to 11 the pillar b is hollow and provided with a cross-bar u forming a bearing for the T- shaped piece which passes through a central aperture therein and is supported upon said cross-bar by a collar 0:. 'r r are the springs for acting on the hinged wings d cl. The head j of the stud is recessed to receive a spring 7L and plate y as before, the plate being provided with cams or studs .2, said plate having a square aperture .2 (see Fig. 11) through which a squared part 5 of the shank 9 passes, so that the two turn together.

When the wings cl cl are expanded, as in the modification illustrated in Figs. 8 to 11, the studs z are forced into the recess 2 see Fig. 9 or hollow portion of the pillar by the spring It so as to lock the wings in position, when open.

Then the wings are to be closed together, as illustrated in Fig. 10, the head of the button or stud is given a quarter turn whereby the projections z z are moved away from the recess compressing the spring and bearing against the under side of the disk av of the pillar. In this position the head of the T- shaped piece is parallel with the hinges of the wings which are brought to the position shown in Fig. 10, by the springs r.

I do not limit myself to the constructions shown and described, it being obvious that various modifications might be made without departing from the spirit of my invention.

IVhat I claim, and desire to secure by Letters Patent, is-

1. In a cuff button, the combination of a pair of hinged wings d each having two cams m formed thereon, a pillar 19 supporting the wings, a head j, a shank g attached to the head and passing through and revolvingfreely in the pillar b, the said shank g having a cross-barn to engage the cams min the wings (1, whereby the Wings are opened and closed by giving the head one complete rotation, substantially as described.

2. In a cuff button, the combination of a pair of hinged wings at having cams m, a pillar b supporting the wings, a head 9', a shank 9 attached to the head and passing through and revolving freely in the pillar b, the said shank 9 having a cross-bar n to engage the cams m in the wings (1, whereby upon rotating the head the wings will be opened, together with a spring connected to the wings for automatically restoring the same to position when the stem has been rotated to free the cross-head from engagement with the cams, substantially as described.

The foregoing specification of my improvements in studs or fastenings for shirt wristbands or cuffs and the like signed by me this 16th day of September, 1893.

JEAN NADAL.
